While I'm waiting on my 3.40 oe-a psp to arrive, I'm trying to shrink all my game .isos as small as I can, as I only have a 2gb memory stick. With some .iso files being over 1gb, I figure this was a good idea. My question is this, what program do you all use to convert your .isos? Also, about how long does the process take, and how much does it generally shrink the file size? And finally, I've heard compression makes some games lag, is that true?
